 +====== Enter Installed System From Install Cd ======
 +
 +1. Boot up with the Gentoo minimal cd.
 +
 +2. Mount your gentoo partitions...
 +
 +<code>mount /dev/sda3 /mnt/gentoo</code>
 +<code>mount /dev/sda1 /mnt/gentoo/boot</code>
 +<code>mount -t proc none /mnt/gentoo/proc</code>
 +<code>mount -o bind /dev /mnt/gentoo/dev</code>
 +<code>mount --rbind /sys /mnt/gentoo/sys</code>
 +<code>mount --rbind /dev /mnt/gentoo/dev</code>
 +
 +
 +3. chroot into the install gentoo environment...
 +
 +<code>cd /mnt/gentoo</code>
 +<code>chroot /mnt/gentoo /bin/bash</code>
 +<code>env-update</code>
 +<code>source /etc/profile</code>
 +
 +
 +====== Add LVM and RAID support at boot time ======
 +genkernel is** Deprecated**  Use sys-kernel/installkernel instead.
 +
 +<code>
 +<del>genkernel --lvm --mdadm --install initramfs</del>
 +</code>
 +
 +===== Install GRUB =====
 +
 +
 +If need To install GRUB, need to enter installed Gentoo system: 
 +[[gentoo_env|Enter Installed System From Install Cd]]
 +
 +
 +and install GRUB2 on both physical disks with RAID support
 +<code>emerge — ask sys-boot/grub:2
 +emerge mdadm
 +grub-install /dev/sda
 +grub-install /dev/sdb
 +grub-mkconfig -o /boot/grub/grub.cfg
 +</code>
 +
 +
 +add RAID support at initial boot sequence
 +add <code>GRUB_CMDLINE_LINUX_DEFAULT="domdadm dolvm" to /etc/default/grub</code>
 +(Gento):
 +<code>
 +GRUB_CMDLINE_LINUX_DEFAULT="domdadm dolvm"
 +</code>
 +
 +list HDD UUID’s
 +<code>blkid</code>
 +
 +add HDD UUID’s to fstab file
 +<code>nano -w /etc/fstab
